WALTER HENRY BROWNING, OF WEMBLEY, LONDON, ENGLAND, ASSIGNOB TO THE BRITISH ADDING MACHINE COMPANY, LIMITED, OF WESTMINSTER, ENGLAND.

APPARATUS FOR ADDING OR CALCULATING.

Specification of Letters Patent.

Patented Nov. 28, 1911.

Application filed November 29, 1909. Serial No. 530,508.

To all whom it may concern:

Be it known that 1, \VAL'rI-m HENRY BROWNING, a British subject, residing at \Vemblcy, London, England, have invented certain new and useful Improvements in Apparatus for Adding or Calculating, of which the followin is a specification.

This invention relates to that type of adding or calculating machine in which the counting is effected for each denomination by a vertically sliding counting plate and an auxiliary plate which are raised a given distance for each unit by means of keys and levers connected therewith, machines of such type being shown and described in Patents Nos. 975933 and 975634, granted to myself and B. T. OBrien, November 15, 1910.

The counting plates are as hitherto constructed arranged to represent units, tens, hundreds and thousands and so on, orpence, shillings and pounds, or dollars, francs, marks or other denomination of money or weights and in describing the machine it is only necessary to describe one set of these plates and their operative connections and the connection of one set with the adjacent sets for the purpose of carrying on from one denomination to the next high-:r denomina tion.

The object of the present invention is to so construct and arrange the operative parts of the machine that the required movement to perform their several functions is given to them by the forward stroke of the operating-handle the backward stroke only releasing the parts or restoring them to their normal positions.

The invention will be fully described with reference to the accompanying drawings forming part of the s ecification.

The main counting plate A and the auxiliary counting plate A are mounted in a movable frame A on iable of moving to and fro as heretofore. The main counting late is provided with rack teeth a on its root edge and ratchet teeth or notches a on its back and also with a lateral projection or pin a near its lower end and a lateral pin or projection (i near its upper end both on the same side between which the auxiliary counting plate A is placed. The pins or projections a a are adapted to engage the auxiliary counting )late A, the lower one a? to raise it and the upper one a to rest upon the top of the auxiliary plate and maintain the main plate in a position corresponding to that to which the auxil ary counting plate A may have been ra sed above its zcro position. The auxiliary countin plate A is made with a plain edge at the rent and provided with notches or ratchet teeth a on its back ed e, which enage with the retaining paw g or catch a v which it is maintained in its ra1sed.po-

sition to receive the main countingplate A end of each type setting plate a cranked arm or lover b is allixed by which it is connected with and raises a rack B hereinafter deshowing one key (lOI'JI'QSSQCl and adding scribed with reference to the printing mech- 5 plates moved into mesh with rack quadi anism.

In front of the swinging frame A (for each set of counting plates A and A) two toothed quadrant levers C (l are mounted loosely on a transverse shaft 0. W hen the swinging or sliding frame A and plates A and B are moved forward the counting uadrant C meshes with the rack a, on the ront edge of the main counting plate A and the type quadrant C with the rack b onthe front edge of the type setting plate 13.. The plates A and B are raised by these quadrants the desired distance corresponding with the value of the key struck. Adjacent to the two quadrant levers 0,0 preferably placed between them aconnectin lever C is also loosely mounted on the sha t c. The counting quadrant is provided with a pin or projection c projecting toward the connecting lever C and the printing quadrant with a similar pin or projection c with which the edge of the lever can engage and the printing quadrant is also provided with a pm or projection c on its other side. The quadrants C and C and the connecting lever C rock or oscillate on the shaft 0 of elevating lever D carrying a transverse rod or bar d which engages all the connecting levers C across the machine, and is operated by a cam d on the cam shaft.

Below each set of quadrant levers C and- C' a controlling bar E is mounted capableof sliding to and fro longitudinally of the machine. The function of this bar is to control the extent of the downward movement of the quadrant levers C and C- accordin to the item to be added at each operation of the keys. The controlling bar E is provided with a lateral projection or pin 6 near to its rear end which engages in a notch c in the lower end of the connecting lever C and as the quadrant levers C C and connecting lever a rock or oscillate downward the bar E is caused to move toward the key board or front of the machine and as they are rocked or oscillated upward the bar E is moved back toward the back of the machine into and reset in normal position. Toward the frontend of the controlling bar E it is fitted with a number of lateral projections or stops e one for each key, which engage the lower ends of the keys K when the latter are depressed. The stops e are set at successively increasing distances from the end of the keys respectively with which they engage such distances corresponding with the value of the several keys so that the distances the controlling bar is permitted to move alre equivalent to the value of the key depressed, The efl'ect of thisis that the quadrants C and C are permitted to rock or oscillate downward an equivalent and consequently the by a resetting lever upward movement to lift the plates will be more or less as the movement downward has been greater or less.

The keys K are mounted to slide verti its raised or normal position holds the look? ing bar is out of engagement with the notches in k of the keys K (see Fig. 1), but

when depressed the lockin bar is is permitted to slide forward y entering the notch in therein and at the same time enters the notches in the other keys to lock them in their position, (see Fl 6). On any key being depressed the rec ing bar 1c? is rocked downward and the releasing key K simultaneously moved by it unt l the notch k therein coincides with the edge of theloqking bar In which enters it spring forward and at the same time engaging the notches of all the keys thereby locking them all but the depressed or operated key in their normal position to prevent a second one being depressed also locking the depressed key in that position. The locking bar In is with drawn again from on agement with the keys 5 operated by a cam g on the cam 'shaft and a cross bar g which engages a pin 9 on the locking bar. A correction lever G is also placed behind the keys K with an arm 9 which also engages the pin 9 by which the locking bar Ia" can be withdrawn and the keys reset should the wrong he he accidentally struck. The

correction ever G by the second arm 9* enthe quadrant levers C C and the control bar E to normal position. The control bar E is held in'normal position against the weight of the rocking quadrant levers G C by a lateral projection or pin on the release key K engaging a notch e? in the underside thereof. W on a key K is depressed the release key K releases the control bar E which slides forward until the corresponding stop 6 strikes against the lower end of the key (see Fig. 6).

Behind the swinging or sliding frame A which carries the counting plates A. A a bolt lever F is mounted to swing or rock on a transverse shaft f, the front end of the the force of a spring f which holds it in ratchet teeth a of the main counting 1% thereby permitting the latter to fal until the top projection a thereon rests upon normal position. The bolt lever F is so placed in relation to the main counting plate A that when the swinging frame A is moved back and the late A is in normal position the first rate iet tooth a engages with the end of the bolt and when the plate is raised one of the otherratchet teeth engages the inclined end of the belt F and the plate A is thereby maintained in its raised position until the bolt is withdrawn.

The bolt. F is provided with a lateral projection or pin I which enters a notch a 1n the back of the auxiliary adding plate when the latter is in normal position.

Above the bolt lever a pawl or catch a. resting on the fixed frame f is pivoted on a transverse shaft and'projects forward to engage the ratchet teeth a on the rear edge of the auxiliary counting plate A when the frame swings back. When the auxiliary counting plate is in normal position the pawl a engages the first tooth and when raised engages one of the other teeth a maintaining the plate in its raised position, see Flgs. 1, 6 and 10.

When the auxiliary counting )late A is in its raised position the back c go engages the projection f on the bolt F and resses the inclined end out of engagement with the late the head of the auxiliary plate A, and in this position the main plate A again meshes with the teethcf the counting quadrant C as the frame swings forward, the auxiliary plate A being released and allowed to drop back to normal position.

Lateral projections I extend from the sides of the bolt F and these are so placed and arranged that when the bolt F is in certain positions the pro'ection f on the side of one bolt extends be ow the projection f on the side of the adjacent bolt of the next higher denomination consequently, it the first bolt lever F be raised or rocked about its fulcrum or pivot the adjacent one is raised a corresponding distance, see Figs. 10 .and ll.

Below the bolt levers F a couple of carry on levers H are pivoted on a. transverse shaft .h preferably one at each side of the machine which supportha carry on bar II (see Figs. 1. 3 and 9). The carry-on bar H is placed transversely under the forward en'lds of the bolt levers and bolts F F and isirocked at each rotation of the cam shaft by a cam I: 'thereona distance equal to one tooth on one unit of the counting plates A.

,notch c-\ therein and when a key is struck,

' key L and connecting link or auxiliary counting plate A out of contact with the main counting plate A, a carry-on rojection h on the underside of the bolt l is brought into position overthe carr v-on bar H so that as the bar is rocked the bolt F is'raised to lift the main counting plate A of the next' higher denomination one tooth which is added to the amount already recorded by that plate. This is ellccted by the lateral projection f" of the one bolt being also brought under the lateral projeclion f" of the adjacent bolt.

In addition to the projection f on one bolt to engage the projection f on the adjacent bolt a vertically sliding pin F is placed in the guide frame f between each bolt F and the retaining )awl a of the auxiliary countin plate A oi the next higher denomination w rich pin is also raised by the bolt. Should therefore one or more denominations be engaged in a carry-on at one time and two or more of the bolts F be withdrawn so that the lateral projection f does not engage with the projection f of the bolt of next higher denomination the auxiliary counting plate pawl a by the .pin.Y is raisedone tooth and with it the auxiliary plate thereby transmitting a carry-on to the main counting plate A-ofthe next higher "denomination. T

, An eliminatin bar ;L is placed to runtransversely of tie machineunder theends of the lower members of thecounting, late quadrants C to engage when lifted with a prevent their falling and the control bar E moves .forward. Ihe eliminating bar L 18 carried between two levers l. one at either side of the machine pivoted on the transverse shaft Z. The eliminating bar]. and lover L are brought into action hyan eliminating lever I placed adjacent to the other'keys. The function of the eliminating ke v.L andbar L is to disconnect the keys K from the 'counting nlates A to render them'non-additive While the type plate quadrantC and typesetting plates B may continue to be operated from the keys to print off a total or to permit of the type setting plates being set-up by the totaling mechanism to print ofl the total. A single eliminating bar L may beempl'oy'ed to 4 traverse the whole inachine or in'a' large machine two or more-eliminating bars TIL with levers and keys L L (seepla'n Fig'fo) may be employed. 'f

The depression of the partial eliminating key L raises the eliminating bar "If Fia 5. au'd engages the adding quadrants ofthe higher denominations of numerals only (disvconnecting "them from the keys. K and the them are struck. This leaves theprinting quad= rants only operative in connection with the I '1 cnterin a notch in a manner similar to that described with reference to the keys K. In addition each, eliminating key L L is locked to Prevent depression after the depression 0 any of the other keys to prevent the eliminatin key being brought into action except w en the other parts are in normal position. This is effected by a transverse bar I which enters a notch in-the key and is carried forward by the movementof the key locking bar is and a pin 7c thereon engaging the transverse barl. The transverselocking bar 1 is carried on two rocking arms or levers Z mounted on the'rockin%shaft Z.- v

ehind the notched releasing key K and between it and the type 1dalatec uadrant C a cipher control lever =is"p1voted. The front end of the lever projects beneath a pin 'm on one side of the releasing key K and from the side of the printing plate quadrant to swing or rock. Lateraljfingers m"- m side.

project from either 'side'of the-cipherflcontrol lever M the finger m! on onesidebeirig set lower than thefingcr mf-onitheother One lever M isrovided for each denomination or bank 0 keys and thefinger in on one lever projects beneath the finger m. of the adjacent. lever of lower denominaticn. The falling of the release key K on any key being struck, raises the rear end of the ci her 'c'o'ntrol lever M out of contact with t e pin 0 on the printing plate quadrantC' permitting it, to. fall one tooth sufiicient to set up the type setting bar one tooth to print 0. The movement of any one cipher control lever also by the finger m raises that ofnext lower-denomination and soon all along the, range of denominations so that allthe-type ls'ettingplates B of lower denomination thanthe keyg-struck are raised suflicie ntidi'stance toprintb when required,

agha tor higher denomination are not moved; I.

-In connection with the use of aseoond or partial eliminating bar L? and-key L for the higher denom nations a connection is made. between the, cipher-control lever M corresponding thereto whirh i :provided with a sliding-iarmgor iingelj 11, a,. his arm or finger pi;

ing-,the movement of the frame A.

verse ly 1s piv the partial eliminating key L and drawn out of the path of the finger m of the next lower denomination to prevent the movement of the type setting plates B, and the printin of 0 or ciphers. Consequently when tie numerals of higher denomination are eliminated and rendered non-additive although they can be used for numberin and printing they are also disconnecte from the cipher control and printing mechanism of the lower denominations.

Below the swinging or sliding frame A which carries the countin and type setting plates A and B a. vertically swin ing plat frame N. is pivoted.- This rame for each denomination carries a stc ped plate N with steps n (1 to 8or 10) 'w ich is capable of sliding to and fro therein to bring one of the steps against a projection or pin a on the main counting plate A corresponding to'the height thecounting )late may be at. The stepped plate N is a so provided with a hook or catch or notch a at the end to engage a pin or projection 11" on the control bar E to connect the two together. In front of the total plate frame N a total unlocking lever N is pivoted one end engag" (with the control bar E and releases t e latter. The total plate frame N and the total unlocking lever N are connected by. a link n with a key or key lever N the depression of which raises the total plate frameN and total plate N into engagement with the controlbar E. The control bar E then moves forward'drawing the stepped plate with it until the latter stops against counting plate. A lever'N pivoted upon the eliminating lever" shaft Z (or other shaft) falls under or into a. notch 41, in the total key N when it is operated and looks it in that position until released by the resetting lever G.

Two total keys N and N are preferably applied either 'of which will perform the functions already described, the second of these N the grand total key-also acts as a dischar e to return the counting plates A A an connecting mechanism to zero. For this purpose a vertically moving discharge plate is mounted in the swinging or sliding frame A with a lateral projection or pin ,1) with which the end 79' of the grand total key N engages. At the upper end the plate is provided with a notch p on the front edge and a notch p on the back edge so that when raised a pin 7) mounted on a slide is drawn into the back notch p and as the swinging frame A moves forward the front notch engages a fixed pin 72 and retains the prate P in elevated position (in;

char e bar P laced tr n. P late swm ing' 'fd' ind the discharge p total and connected therewith by a pawl and lever 77 which when the discharge plate P is in normal position enters a notch p therein and when the discharge late P is raised lies in the path of the Et ge of the plate. The swinging discharge bar P extends across all the bolt levers F engaging anotch or projection f thereon. The operation of the grand total lever N 5 raises the discharge plate P and the sliding pin p enters the notch 12 in the back edge. When the frame A next moves forward the notch in the front 'edge of the plate P passes over the fixed pin 7) which retains the plate P in its raised position and as the frame A next moves back the discharge lever in its path is pushed back and the swinging discharge bar P is carried back with it and all the re taining bolts F are moved back releasing the counting plates A A and permitting them all to return to zero.

A total cipher control lever R of hell crank shape is pivoted below the total late frame N. The arms of the lever R are ormed with a hook r at the end of one and a catch 1" at the end of the other. The hook or catch r engages a notch r formed below the teeth on the front edge of the main counting plate A and the catch r engages the tail of the type quadrant C. A tail 1' is provided to the lever R with lateral projection r on one side and lateral projection r on the other side. The projection 7- extends below the projection 1- of next lower denomination and the projection r extends above the projection of the next higher denomination as already described with referraised the levers R come into action, the

hooked ends r fall into the notches r of such of the counting plates as are to the left of the plate of the highest number recorded thereby preventing the setting up of the t pe plate B and the printing of 0 to the left thereof.

At one side of the machine parallel to the control bars E a sliding locking bar E is mounted. This bar carries a square stud e and is moved to and fro with the transverse locking bar I of the eliminatin keys L and L being connected to the lever 5 by a pin 6*. The square stud or pin 0 enters a notch n in the link a which connects the total keys N N with the total plate frame N. When thus locked the total keys N N are prevented being operated should any of the denomination keys K be depressed.

It may be necessary to operate or rotate the handle of the machine several times to make all the changes necessary to obtain -end is projected forward through a slot in the case into sight of the operator to indicate that the total key N or N is free and may be depressed.

Above the bolt levers F a second transverse rocking barS' is placed with which the projection S" engages.' The bar S is mounted on a rocking lever a which extends upward and engages a pin 8' at the end of the indicator or locking slide bar S conscqucntly when any one of the bolts F and bolt levers F are moved back, bar S is drawn back with them. 'On the side of the slide bar S a pin or projection 8 extends laterally so placed that when the slide bar S is drawn back the projection a is placed over the cud of the connecting link n and plcvonfs its upward movement and thereby prevents the manipulation of either of the trial ltcys X N. Should therefore any one of the bolts I*" be moved back by a divide or transfer taking place the indicator or lccking slide bar S will he moved backward and out of sight; should on the other hand the total be complete the indicator or looking slide S would not be moved and the total key would be free to be depressed.

On the key resetting lever G a trip lever g is pivoted with which the actuating cam g engages, the lever 9 may be moved out of the path of the cam y: preventing the resetting of the keys which have been depressed allowing the repeating or re-adding of the number again and again. The trip lever is movcd out of the path of the cam g by a repeat key G which can be moved to and fro as required a pin 9' thereon engaging the pivoted tri lever g".

The retaining pawl b for the type lifting plates B is withdrawn by a projection or pin 12 on the slide b of the carry-on motion or it may be withdrawn by a, key or lever provided for the purpose.

The elevating lever D which returns the quadrant levers to their normal or first position is locked, when oscillated by the elevating cam to its full extent by a lever (l' which is raised and lowered by a rojection d on the cam d and remains so ocked until released by the raisin of the lockin lever on the return stroke 0 the operating andle.

The swinging or sliding frame A which carries the counting plates A A is locked in its normal or backward position by a locking lever A which is raised and lowered by a cam a on the cam shaft. This cam comes into operation during the early part of the forward movement of the handles The mechanism fogdisplaying the numbers and for printing comprises a number of disks or wheels T with either the numerals or the type or both on the periphery. It is preferred to have both on the same periphery so that a numeral can be displayed while the corresponding type is printing.

Each type disk T carrying the type numeralsupon its periphery is operated by a rack B gearing with a pinion T on the side of the disk or on the disk spindle. An extending arm or finger t affixed to the rack rests upon a bracket 6* attached to the top of the type setting plate B and the rack is moved vertically thereb consequently the movement of the rack 1; and of the type disk corresponds with that of the type setting plate B.

In the periphery of each type pinion T notches t are cut corresponding in number with the numerals or type and with these notches a blade 15 engages thereby locking the pinion T and type disk '1 in correct position during the printing operation and securing alinement of the type. The type disks T are pivoted in a carrier frame or bracket T singly or in groups which carrier is also pivoted thereby permittin the disks to be raised independently, sing y or in groups, against the rinting platen.

The racks B move reely in guide bearings and the racks may be roundedrat top to clear the rim of the type disks T and the type disk carriers T are mounted on a transverse shaft 5* and rest on a guide bracket.

The disk carriers T are raised by a series of cams T on the cam shaft each cam acting on a runner t on the foot of the carrier. The cams T are arranged to elevate each carrier and disk in succession and are mounted on the cam shaft so that they may be together moved laterally thereon. Between each cam sufficient space is provided to permit of the runner t on the carrier passing between. The series of cams are moved laterally on the shaft after the printing has been efl'ected by a bell crank forked lever T operated by a shaft cam t onthe same cam shaft suflicient distance to allow the carrier runner to drop between them and render the cams inoperative on the backward stroke of the handle. The bell crank lever T is moved in one direction by a spring against the aced in a similar carrier is placed alongside of the printing disks to print a. star when the keys K-are disconnected or eliminated and used as non-additive to indicate that the numbers printed in such lines are ndt mcluded in the totals. This star disk T is operated by a type setting plate operated by quadrant lever U which is brought into action when the eliminating key L is depressed, and the bar L engages the counting quadrants C. 5

On the periphery of each type disk T in addition to the type are inscribed a num ber of indicating numerals which primarily indicate the numeral corresponding to the value and denomination of the key depressed and indicate across from one to the other the last amount-added to the transaction. The same numerals may be employed to indicate the total amount of the sum or trans; action.

A printing platen or roller W is mounted in suitable bearings above the type disks T with a paper roll and ink or carbon ribbon and means for moving the paper and ink ribbon, which may be of any ordinary con-' struction such as employed in type Writing machines.

A carriage VV' is mounted above the printingdisks T to carry the platen W and the paper upon which the items are printed. This carriage has a movement across the machine and friction feed pinions, pawls or other mechanism for movin the paper forward. The carriage may be uilt up of sides connected by stretcher bars with rollers thereon.

The carriage W moves freely without slack between each set of rollers. A notched locking bar w is fitted to the carriage into I the notches of which a locking lever to enters riage will then be free to move across the machine operated b a spring and when a fresh or any notch o the notched locking plate shall present itself the. locking lever will be returned by means of its spring. A paper tear off plate, plain or serrated, is placed across the front of the carriage and secured to the forward ends of the brackets and a paper guide w is attached to the underside of these brackets. Bearing blocks are fitted to the ends of the platen shaft and drop into the brackets and may be adjusted thereon.

The paper feed motion X on the carriage is similar to that employed on type writers with a spacing device to allow of two or more spaces of lines to be obtained. This feed motion is provided with a depending lever in to engage a transverse rocking ba'r mounted in the frame of the printing mech anism. This bar is rocked by a cam w on the cam shaft and a lever m pivoted to the.

frame side and a link x, a suitable ink ribbon feed is connected thereto and operated thereby.

On one of the side frames is mounted an ratchet wheel has numerals from 1 to 100 (or as many as are desired) on its periphery and is cut with ratchet teeth, one tooth for each numeral which ma be on the wheel.

The indicator wheel l is for the pur use of indicating to the operator of the mac line the number of times the handle of the machine shall have been rotated and so enablesuch operator to print successive columns of figures which shall be of the same length or number of lines.

cator wheel onetooth and present a fresh numeral to the operator.

A retaining pawl 'y' is mounted on the main frame of the machine and serves to retain the indicator wheel after it is moved by the feed lever.

Both the feed pawl and the retaining pawlhave extending arms which are adaptedto come into contact with suitable pins carried by the release lover or bar. Therefore when this release lever or bar is moved downward these pins will take the feed and retaining pawls out of the teeth of the indicator ratchet whorl and leave same free to return to zero. clock or other suitable spring attached to the hub of the indicator wheel and the main frame. $uitable stops are provided to position the indicator wheel at zero.

in order to prevent the indicator ratchet wheel V from being advanced or rotated more than the desired number of numerals ornumbcr of ratchet teeth, and so prevent overwinding of thei'etnrning spring, a blank piece 1 without teeth is formed -n the side of the indicator wheel which'prevents it bring moved farther by the feed pawl Y, and therefore although the handle of the machine may go on working the indi-- cator wheel will remain stationary until it shall be alto-red to return to zero when release bar i.-- moved.
